The National Weather Service at Sterling, VA has issued a Freezing Rain Advisory for Annapolis, Baltimore, and Washington effective tonight and early Wednesday morning. After morning sunshine, increasing clouds this afternoon will give way to freezing rain later in the evening. High pressure to our north will funnel cold air down the coastal plain tonight, and a southerly flow around low pressure will bring warm air aloft. As precipitation falls into the shallow layer of cold air at the surface, rain will freeze upon impact. The effect of "cold air damming" will result in a period of freezing rain through Wednesday morning. To the north, more significant icing is expected to occur. As a result, a Winter Storm Warning is in effect for areas to the north and west of Baltimore and Washington. Temperatures will gradually rise above freezing by early Wednesday morning and all precipitation will change to rain showers; however, icy conditions may be present around the area during the morning rush depending on the time of the changeover from freezing rain to rain. Our weather improves on Thursday and Friday with plenty of sunshine; however, temperatures will be cold with lows in the 20s and highs in the 30s. Unsettled weather returns to the Middle Atlantic region this weekend with a chance of rain or snow showers on Saturday, and a chance of more significant winter precipitation by Sunday evening.
